Authority to assert origin is not evidence that origin is true.
Prior claims: Missing provenance should be treated as synthetic; human-origin scopes form a downgrade ladder; signed, encrypted, expiring policies make human origin verifiable; a disputed hash invalidates a claim.
Corrected position: Missing provenance means unknown origin. Process evidence, attributable declarations, accountability, and authority are separate dimensions. Capture, authorship, approval, and AI assistance can coexist. A signature binds a declaration to a key under stated assumptions; it does not establish authorship. Disputes require governed review. Claimed issue time is not independent time evidence, and historical evidence does not share the lifecycle of current permission.
Reason: The retype counterexample passes the original policy checks: a person can retype or revise AI-produced text and issue a valid signed claim. The cryptography protects the record but does not establish the truth of its creation claim.
